Logitech (www.logitech.com) has expanded its keyboard lineup with the Logitech Bluetooth Illuminated Keyboard K810. Compatible with iOS, Windows and Android devices -- and with a layout designed for Windows 8 -- this rechargeable keyboard uses Bluetooth connectivity to pair with up to three devices simultaneously.

Your keyboard can be connected to your PC, tablet and smartphone and you can switch among them with the push of a button, says Mike Culver, vice president of brand development for consumer computing platforms at Logitech. To increase the keyboard’s usability in low-light conditions or at night, the keyboard boasts auto-adjusting illumination.

It also uses proximity detection to turn on the lighting when your hands approach it, and automatically dims or brightens, depending on the amount of light in the room. The K810 is USB rechargeable with 10 days of battery life on a full charge (based on varying user and computing conditions). Thanks to the USB cable, you can even use your keyboard while it’s recharging.

The keyboard also features an on/off switch, and its battery-indicator light helps you manage power so you know when it’s time to recharge. The Logitech Bluetooth Illuminated Keyboard K810 is expected to be available in the U.S. and Europe in October and November, respectively, for a suggested retail price of $99.99.
